I had that combination and changed to all rope halyards. On Giu and SD's advice, I used Dyneema for reduced stretch and higher strength / lower diameter. As its about the same diameter as the wire it replaced, the blocks do not seem to cause a problem.
There was no problem pulling the new halyard through with the old tail. I used the sleeve off a piece of old rope whipped onto the old tail and the new head. Then pulled it through from the old head end, which had a swagged eye on it.
